I was fixing a flat yesterday on my tubeless DH rims (823s?) and was in the process of pumping them up. I was using a Maxxis tubeless tire with some Stan's home-made slime stuff in case of punctures. Noremally, at a certain pressure you hear the little pop of the tire seating on the rim, but not this time. Curious!!

I kept on pumping... Nothing...
30lbs
40lbs
50lbs
55lbs

At about 55lbs I stopped and picked up the wheel to listen for leaks or something. As soon as I got the tire up near my head...

























BOOM!!!

The tire blew right off the rim. It sprayed stan's mix all over my face, in my hair, on my clothes, and up to 15feet down the driveway.
It even exploded with enough force that it somehow even blew up my hub!! Pawls were on the ground, the casette was over in the grass...

About 15 seconds later, my neighbors started soming out and exclaiming WTF is going on!! There I am covered in green slime, my hair was blown backwards like david lynch, hub parts and slime all over the place, I even cut/bruised my hand some how. Everyone kept asking me if I was OK... And this was only 55lbs of pressure!!
So I guess the lesson here is that you should maybe bounce the tire a few times before you put it up to your face. I could have easily gotten slime in my eyes. YUCK!!

I'll probably get a knock on the door later today from Homeland Security.

Ahaha, i did the same thing in my basement when my michelin blew out (while using stans).
Nevertheless my mom came running downstairs to see what happened, that stans stuff i hard to clean up (super sticky)

 

[Slugman]

Damn... glad to hear you were not seriously hurt.

Damn... glad to hear you were not seriously hurt.

yea for sure i have to snicker but you could have really been hurt.

I've heard a lot of these stories lately.

I think the lesson is to use tubed tires!

RFTM

Tire dimensions and maximum inflation pressure

TIRE SIZE MAXIMUM PRESSURE
inches bars psi

2.1 3.70 55.00

2.2 3.50 52.00

2.3 3.30 49.00

2.4 3.20 47.00

2.5 3.00 44.00

2.6 2.80 41.00

2.8 2.50 36.00

2.9 2.40 34.00

3.0 2.20 32.00

If you are seating the bead, I would do it by hand with larger tires at lower pressures

too funny...glad you survived!

 

[JRB]

I did it on a Rigida rim too. I nearly broke my thumb and got cut to hell. I got covered with stan's. It was all over the garage. Sucked.

It was only a 2.3, so I was still fairly close to the reccomended Max perssure... And I wasn't even riding on it, so there was no pressure increase from my weight.

 

[motomike]

crazy stuff man. Couple of months ago, something similar happened to me. I was at work inflating a 700c clincher wheel after replacing the tube. Got it to around 80psi when it decided to explode. I couldn't hear for several minutes afterwards. The best part? There was a cop standing near me looking at stuff, and when it blew, he had his gun halfway out, ready to go!

 

[Senôr Lopez]

One time when I was little I popped a balloon by accident. It sucked.

 

[dh girlie]

That's hysterical...

 

[Ciaran]

I think I'll stick to tubes. I don't want "the man" coming after me for blowing things up.

 

[hooples3]

unfortunately i did it with a tube tire.. i am in my house, filling my tire after just changing it and talking on the phone not paying attention to what i am doing.
BOOM!!!! scares the sheet outta me and my wife winds up dropping a glass pitcher on the floor....

Nah, I'd give them six days.


MBC had a road tire blow up on her Monday morning around 9:00. The neighbors must have thought we were shooting a gun.

If they're going to come after you, at LEAST blow things up properly so you have the satisfaction thereof.

 

[Acadian]

been there...

done that....

ask Carlos (Joe Pozer) - I thought I was going to loose my ears. Really scared the hell out of me.

Yeah, but you weren't covered in goop...

had that done multiple times. worst was 2 months ago on my street bike at jiffy lube in front of 4 hot ass girls. was filling up the 4runners tires and noticed the rear 2.4 holy roller was low so i pumped it up. i run it tubeless on an 823 with stans and run really really really high pressure. anyways tire blew off the rim, almost broke my hand (so bruised i coulnt use it for a week) stans all over car, bike, me and hot girls, and i couldnt hear for about 2 minutes out of my left ear. bad times.

 

[Dartman]

And this was only 55lbs of pressure!!

That's 55lbs per square inch. There's a lot of square inches inside a tire.

I figure about 33,000 lbs total in the inner surface area of the tire.

[TreeSaw]

LOL!!! Glad to hear you weren't seriously hurt!

 

[Slugman]

All of this is very timely informations since I'm building my new rear wheel (well new to me...) with that 823 I got from wheelieholz.

Maybe I'll keep tubes in there after all...

 

[lovebunny]

this one time at northstar my buddy was changing his tube and hes pumping it up and it starts to bulge out. and my other buddys like "RELEASE THE PRESSURE! RELEASE THE...BOOOOOM!" that sucked

 

[Cooter Brown]

after a race last fall everyone was sitting around waiting on the award ceremony, and I had changed my flat before my last run, so I went to the top, did my run, laid my bike down and after about 30 minutes........BOOM!! Sounded like a damn shotgun, everyone standing around jumped, it looked like a mosh pit or something

That's the best!

 

[ottomatik]

ha ha back in the day i was at my lbs and one of the guys was at the counter airing up some guys tire. the thing blew up blowing green slime all over the bike mechanic and ceiling...memories

 

[JRB]

That's the best!

it one ups the garage deal I had. All over the hot chicks. hahahahaha

 

[skinny mike]

it one ups the garage deal I had. All over the hot chicks. hahahahaha

i dunno if they were hot how could you be so sure that that was stans?

 

[Changleen]

Funny stuff. Splattering white goop over hot girls: Teh awesum!

 

[PatBranch]

One time, I was pumping my tire up after replacing the tube. It seemed like I pumped more than was in there. So I bounced it on the ground. All of a sudden, the tube came out under the sidewall and it kept getting bigger, then it blew up and slime was everywhere.
